Gmail not sending with env variables in Rails 4 project, but env variables are displayed in console

问题

I am working on a tutorial about ActiveRecords and needed to configure ActionMailer.

I have Environmental Variables configured in ~/.bashrc and this system has been working reliably.

I configured everything in the development.rb

development.rb

config.action_mailer.delivery_method = :smtp

config.action_mailer.perform_deliveries = true

config.action_mailer.default_url_options = { :host => "localhost:3000" }

config.action_mailer.smtp_settings = {
    address:              "smtp.gmail.com",
    port:                 587,
    domain:               "gmail.com",
    user_name:            ENV[ "GMAIL_USERNAME" ],
    password:             ENV[ "GMAIL_PASSWORD"],
    authentication:       "plain",
    enable_starttls_auto: true
}

My contact_form.rb model is:

class ContactForm < MailForm::Base

    attribute :name, :validate => true

    attribute :email, :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i

    attribute :message, :validate => true

    # Declare the e-mail headers
    def headers
        {
            :subject => 'ArcadeNomad - Contact Request',
            :to => ENV[ "OWNER_EMAIL" ],
            :from => ENV[ "OWNER_EMAIL" ]
        }
    end

end

When I test everything in rails console i get:

Machine:dev_arcadenomad_com Account$ rails c --sandbox
Loading development environment in sandbox (Rails 4.2.1)

>> contact = ContactForm.new(:name => 'Name', :email => 'SomeMail@domain.tld', :message => 'I love ArcadeNomad!')

>> contact.valid?
=> true
>> contact.deliver

  Name</p>

  <p><b>Email:</b>
  SomeMail@domain.tld</p>

  <p><b>Message:</b>

=> true

But no mail is delivered.

If I hardcode my credentials into development.rb everything works. When I test for ENV[ "GMAIL_USERNAME" ] in rails console my mail credentials are displayed correctly.

What am I missing?
